Aim of study (acc. to editor)

To investigate the immediate influence of low frequency modulated high frequency electromagnetic fields on regulatory patterns in the state of relaxed wakefullness. Magnetoencephalogram, heart frequency and ventilatory parameters were studied.

Main outcome of study (acc. to author)

The differences in magnetoencephalogram, heart frequency and ventilatory parameters before and after application of low frequency modulated high frequency electromagnetic fields indicate that the effects can be explained by an influence on the common brainstem system. The common brainstem system is part of the central nervous system which organizes and regulates the prerequisites for the execution of meaningful behaviour.
